He served one year of probation and his record was expunged under the Holmes Youthful Trainee act. He also sat out the 2010 season.

Sims was asked Friday about his interview with the Lions and volunteered that the incident was a talking point. He expounded on his version of the events:

"My father had purchased me a computer for Christmas when I lived with him in high school. Some of my classmates saw it, they asked where i got it from. My dad was a professor at U of M, so he had the power to purchase computers at a discounted rate. It turned out that my dad was never putting the money back into the account. He was using Michigan's funds to purchase computers, and it was humiliating to me. My dad got fired from his job and it was all pretty much a disgrace. Things happen, and you just have to learn how to build off them."

Dion Sims said he has learned from his mistakes and has been open about them as he meets with NFL teams.

"It was just all about being naive and being a kid at the time -- not really knowing what's going on," he said. "It's a mistake that I will never make again."

Sims caught 36 catches for 475 yards and two touchdowns last season at Michigan State, while also missing some time due to an ankle injury. ESPN's Mel Kiper Jr. said last month the tight end could be a third- or fourth-round prospect if he has a strong combine.

CBSSports.com ranks him as a fourth-round prospect and the No. 7 tight end.
